[Feature request] Include port and Adjust scheme for localhost in NIP96 json api_url

[eyemono-moe]

Currently, the api_url in NIP96 json and the nip94_event URLs do not include the port specified in the configuration file. As a result:

• When running nostrcheck-server on localhost:3000, the URLs are set to https://localhost/***, which doesn’t allow proper access.
• Additionally, even if the host is set to localhost, the URLs are forced to use https, which can be incompatible with local testing environments.

Feature Request

1. Port inclusion: I would like the URL to include the port specified in the nostrcheck-server configuration file.
2. Localhost Scheme Adjustment: When the server is configured to run on localhost, the URLs should use http instead of https.

Although unnecessary for deployment, this change would greatly assist development and testing in local environments.
